Regarding waste fermentation tanks. Conventional technology> Various types of devices have been proposed for fermenting organic waste such as garbage and composting, such as multi-stage fermenters, horizontal rotary fermenters, and fermenters with stirring arms. ing. In order to efficiently ferment organic waste aerobically, a rotating tank is installed or a stirring arm is installed in the tank to stir the waste, but in order to drive the rotating hinoki or stirring arm to rotate, It requires a large amount of power, has a large structure, and when waste is kneaded by stirring, some of the waste may solidify, reducing air permeability, and fermentation may not necessarily be carried out efficiently. Therefore, fermenters were reconsidered, in which organic waste is placed in a vertical tank and the contained waste is left to ferment without using a rotating tank or stirring arm.
It has been proposed that the bottom of a cylindrical vertical tank is filled with gravel, a ventilation pipe is placed inside the tank, and a ventilation pipe is further provided in the upper part of the tank (for example, Japanese Patent Laid-Open No. 59-307
Publication No. 98). Problems to be Solved by the Invention> However, when the above-mentioned fermentation tank is installed outdoors in a cold region, in addition to the tank having good thermal conductivity, the bottom of the tank is covered with gravel. However, the internal fermentation temperature was strongly influenced by the outside temperature, and the decrease in internal temperature inhibited the fermentation of organic matter. In addition, the presence of gravel at the bottom increased the weight of the tank, requiring a stronger base structure and making it difficult to move. The present invention was made in order to solve the above problems, and is an organic waste that has good heat insulation properties, is lightweight, and has good ventilation inside the tank and can perform efficient aerobic fermentation. The purpose is to provide a fermenter for fermentation. Means for Solving the Problems> In order to achieve the above object, the organic waste fermentation tank of the present invention has a vertical storage tank with a large number of ventilation holes bored in the side wall, and the outer periphery of the storage tank. An insulating material is placed so as to surround the storage tank, and a gap for ventilation is formed between the outer circumferential surface of the storage tank and the insulation material by continuously arranging a net to the bottom of the tank. A perforated plate is placed near the bottom of the
The space below the perforated plate is filled with foamed or hollow plastic granules, and the space below the perforated plate is provided with an air pipe that blows out air from an external blower. It consists of In this organic waste fermentation tank, organic waste such as food waste is put into the storage tank, fermentation bacteria are put in at the same time, and the blower is operated to send air into the tank from the air pipe. Air fermentation takes place. During this time, a small amount of outside air enters through the gaps in the insulation material through the numerous ventilation holes provided in the side walls of the storage tank, allowing aerobic fermentation to take place well throughout the tank. In addition, the storage tank is surrounded by heat insulating material, and the bottom is lined with foamed or hollow plastic granules, so the internal heat retention is good, and even in cold regions, the air supplied can be slightly warmed at the start of fermentation. Examples of the present invention will be described below based on the drawings. Figures 1 and 2 show a fermenter. 1 is a vertical metal box-shaped storage tank, and a heat insulating material 2 is provided on the outer surface of the side wall and bottom wall so as to surround it, and a stainless steel etc. Furthermore, the side wall of the storage tank 1 is provided with ventilation holes 4 as shown in FIG.
A large number of holes are bored in the side wall, and a metal net 5 is continuously provided on the side wall of the wall on the side of the insulation material, that is, on the outside, to the bottom so as to form a gap for ventilation therebetween. Therefore, the inside of the storage tank 1 is communicated with the outside air through the gap between the ventilation hole 4 and the net 5. In addition, a plurality of drainage holes 6 are drilled in the bottom wall of the storage tank 1, which communicate through the heat insulating material 2 and the outer panel. Further, at the bottom of the storage tank 1, foamed or hollow plastic particles 7 (centered or hollow plastic spheres or polyhedrons with a diameter of about 10 to 30 ms) are spread to an appropriate thickness (covered with a large number of holes). The provided perforated plate 8 is arranged as a bottom plate.
The diameter of the granules 7 is, for example, larger at the bottom and smaller at the top to filter out dirt and improve water flow. Air pipes 10 are arranged at appropriate intervals on the lower side of the perforated plate 8 (the part where the foamed or hollow plastic particles 7 are arranged), and the particles are passed through the holes provided on the lower side of the air pipe 10. Air is sent around the body 7. Further, an air pipe 11 is disposed inside the storage tank 1 along its side wall surface, and the air pipe TO, IT is connected to the discharge side of an air blower 12 such as a pump or blower installed outside. This blower 12 is controlled by a timer, sucks in outside air at regular intervals, and sends the air to the air pipes IO, 11. In the winter, a heater such as a heater is connected to the intake pipe of the blower 12, and the outside air is heated and blown out. In that case, the fermentation temperature in the tank is detected, and when the optimum fermentation temperature is reached, the heater is controlled to stop. The upper opening of the accommodation a1 is closed by the lid 13,
The lid 13 is provided with an exhaust pipe 14 equipped with a deodorizer. In addition, as shown in Fig. 2, a door 15 is provided in a part of the lid 13 to form a waste inlet, and a waste outlet is formed by a 5i116 provided at the bottom of the side wall. ．． Although not shown in the drawings, in order to take out the waste, a screw conveyor or a discharge rotating blade is installed horizontally in the lower part of the storage tank 1 from the take-out port.

移動も容易となるFermentation tanks configured in this way are usually installed in two or three units side by side, and a large amount of food waste such as leftover food and vegetables taken out from school lunch centers etc. is first stored in storage tank 1 of the first fermentation tank. fermentation bacteria are added at the same time. In the fermentation tank, a blower 12 is operated by a timer at regular intervals to promote fermentation while sending air into the storage tank 1 from air pipes 10 and 11. During cold weather, such as in winter, heated air is sent into the tank using a heater to efficiently raise the temperature at the start of fermentation. When the temperature of the organic waste in the tank rises to about 35°C to 40°C, the storage tank 1 is surrounded by a heat insulating material 2, and the bottom is lined with foamed or hollow plastic particles 7, which have good heat retention. Therefore, there is no need for long-term heating even in cold regions, and with an appropriate temperature and an appropriate amount of air sent from the ventilation hole 4 in the side wall of the storage tank 1 through the air pipes 10, 11 and the net 5, Aerobic fermentation takes place well in the tank. For example, food waste from school lunch centers, etc. is stored in the storage tank 1 every day.
If the organic waste is put into the tank first, fermentation will proceed in order from the organic waste at the bottom, and the volume will be reduced to 50-10% of what it was when it was put in, in 8 to 15 days. Therefore,
Although it depends on the size of the fermenter and the amount of food waste, even if food waste is put into the storage tank 1 every day, it will be able to store enough food waste for one month. Then, when the first fermenter is full, the raw goa a is put into the second fermenter, and the organic waste in the first fermenter is completely fermented over the next month. Then, the door 16 for taking out the fermenter is opened, and the fermented and composted organic matter is taken out from the bottom of the storage tank 1 using a screw conveyor or rotating blade. Effects of the Invention> As explained above, according to the organic waste fermentation tank of the present invention, a large number of ventilation holes are provided in the side wall of the vertical storage tank.
A heat insulating material is placed around the outer periphery of the storage tank,
A ventilation gap is formed between the outer peripheral surface of the storage tank and the heat insulating material by continuously arranging a net up to the bottom of the cypress, and a perforated plate is installed near the bottom of the storage tank. The space below the perforated plate is filled with foamed or hollow plastic particles, and the space below the perforated plate is filled with
Since it is configured with an air pipe that blows out air from a single blower installed outside, it is possible that the air will not flow from the air pipe as well as from the numerous ventilation holes provided on the side wall of the storage tank through the gaps with the insulation material. However, since outside air enters the tank,
Aerobic fermentation takes place well. In addition, the storage tank is surrounded by insulation material and the bottom is lined with foamed or hollow plastic particles, so the internal heat retention is good, and even in cold regions, you only need to slightly warm the air at the start of fermentation. This allows the proper fermentation temperature to be maintained and the fermentation to continue smoothly. In addition, compared to conventional fermenters with gravel at the bottom, the weight of the fermentation tank can be reduced.
